Sand it off with some 80 grit. Then 150, then 220.

I recently bought a used boat that has had Cetol applied to its teak
(companionway boards, handrails, helmsman seat, etc.). The Cetol has not
been
kept up and needs to be refinished.

Is it best to sand off all the old stuff or remove it with a chemical
removal
product?
